ASoC: SOF: Intel: only detect codecs when HDA DSP probe

2025-08-29T08:50:37+00:00

SDW codecs use the global HDaudio WAKEEN/STS to detect wakes since LNL. But the wake event is handled in the SDW driver. We should only clear WAKESTS for the HDA and IDISP codecs that was detected when HDA DSP probe. The SoundWire codec will be included in the codec_mask if we read the STATESTS register when a SoundWire codec wake event happens. The commit avoid updating bus->codec_mask in resume to not clear WAKESTS of SoundWire codecs.

ASoC: SOF: Intel: split codec mask detect and programming UNSOL

2025-08-29T08:50:36+00:00

We only need to detect codec mask in probe, but need to program UNSOL in probe and resume. We will detect codec mask and program UNSOL separately in the follow up commit.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

ALSA/ASoC: Intel: clarify Copyright information

2024-05-07T01:37:51+00:00

Merge series from Pierre-Louis Bossart : This patchset does not change any functionality. It only clarifies the Copyright information in ASoC/HDAudio contributions, where an "All rights reserved" notice was mistakenly added in a number of files over the years, likely due to copy/paste. The Intel template never included this statement.

For some reason a number of files included the "All rights reserved" statement. Good old copy-paste made sure this mistake proliferated.

ASoC: SOF: Intel: start splitting top-level from common parts

2024-05-05T14:45:45+00:00

The existing code relies on the 'HDA_COMMON' module and namespace. We need to start splitting top-level parts from the low-level ones, otherwise we will not be able to reuse the low-level parts DMA support for SoundWire/BPT. In the end the dependencies will be: +----------------------------------------------+ | | | v sof-pci-intel-xxx --> sof-intel-hda ------------> sof-hda-common | ^ | | +-> soundwire_intel --> sof_hda_sdw_bpt This patch adds the initial split between the sof-pci-intel-xxx modules and the common parts, in a follow-up patch we will further split the HDA_COMMON parts Since the PCI modules are not all independent, i.e. the CNL parts are also used in JSL and TGL, additional Kconfig and namespace modules were added.

ASoC: SOF: Intel: hda-ctrl: only clear WAKESTS for HDaudio codecs

2024-04-04T19:25:40+00:00

When a PME wake happens due to a SoundWire wake, we currently clear all WAKESTS bits during the resume operation initiated by the PCI subsystem. As a result, we are unable to identify which SoundWire links need to be resumed and don't properly handle jack detection. This patch only clears the WAKESTS bits for the HDaudio codecs detected earlier. Note that we still clear all WAKESTS bits unconditionally in hda_dsp_ctrl_stop_chip(). The existing behavior is potentially racy if e.g. a jack event happens during a suspend routine, but there's a risk of breaking shutdown or reboot sequences so the code is left as is for now.

ASoC: SOF: Intel: hda-ctrl: add missing WAKE_STS clear

2024-04-04T19:25:37+00:00

For some reason, the programming sequences in the SOF driver do not include a clear of the WAKE_STS bits before resetting the controller. This clear is not formally required by the HDaudio specification, but was added to harden the snd-hda-reset back in 2007. Adding this sequence back avoids an issue reported by the Intel CI.
